Stop losing sales to out-of-stock products. Substitutions lets you automatically replace unavailable variants with alternatives you define. The swap happens after checkout during order fulfillment. Customers complete their purchase normally and notice nothing different. Set multiple substitutes per product and control priority order. The app manages inventory settings for you, keeping products sellable when backups exist and stopping sales when options run out. Track activity in your dashboard.
